Citric Acid in Skincare: A Mild Exfoliant with Brightening Benefits

Citric acid doesn’t just belong in citrus fruits—it’s also found in many modern skincare formulas. As a gentle alpha hydroxy acid (AHA), citric acid is known for its ability to smooth, brighten, and balance the skin without the intensity of stronger exfoliants. If you're building a routine with gentle resurfacing benefits, citric acid might be the AHA your skin can tolerate daily.

What Is Citric Acid?

Citric acid is a naturally occurring AHA derived from citrus fruits. In skincare, it functions as a mild exfoliant, pH adjuster, and antioxidant support ingredient, helping maintain both the performance and stability of products.

How Citric Acid Works in the Skin

As an AHA, citric acid loosens the bonds between dead skin cells, allowing them to shed more easily. This promotes smoother skin, encourages cell renewal, and can help improve the look of dullness or uneven tone over time.
